I've got a cracked crown on a red brick chimney. Also, the mortar
between the brick is coming loose.

The cracks on the crown run right down to the red brick. Is it
necessary to chip off the old crown and replace it entirely? Or is
there a product to seal the cracked areas on the crown?

Thanks in advance.


FWIW:
The approx 16 inch by 24 inch concrete cap (it's about four inches thick)
that I poured myself some 25 years ago after a mason built our two flue
chimney, developed a small crack years ago.
Worried about water and ice cracking it further I caulked it using

something

from a tube of fairly ordinary outside caulk. Checking it occasionally it
appears to have worked for the last ten to fifteen years without further
attention.
Other opinions may vary.

Ditto They make 100% silicon 'concrete' caulk which, I suspect, is just a
colorant added. Mine is holding up quite well with exstensive use (read:
many, deep cracks) for the past 3 years.

You make a total mess out of a thread when you top post and don't
snip/edit quoted text as needed. Thank you.
